ÖNORM B 5113

This document specifies requirements for solid-wall piping systems with multilayer wall construction (PP-ML) made of reinforced polypropylene compounds or polypropylene blends for gravity-operated, buried sewerage systems and pipelines. Furthermore, this document establishes terms, nominal sizes, dimensions, requirements, tests, and self-inspection for these piping systems. This document is applicable to piping systems with or without molded sockets and provides recommendations for the color coding of the piping system. Additionally, it includes requirements for fittings manufactured either by injection molding (IM) or by hand lay-up (HL). This document applies to the use of sewerage systems and pipelines for gravity drainage systems that are: — Outside the building structure (application code "U"), and — Inside the building structure (application code "D"). NOTE: The labeling of both application areas is indicated by "UD" on the pipeline parts. Piping systems that can be attributed to ÖNORM EN 14758-1, ÖNORM EN 13476-1, ÖNORM EN 13476-2, or ÖNORM EN 13476-3 are not covered by this document
